It is a better option, but try reading and watching tutorials in advance. If you're patient and follow the correct steps, then you can't go wrong.
Here are some steps:
-choose the pc configuration - make sure that the components are compatible and that you're getting the best components for the money. This forum can help.
-read the board's manual and identify the headers and ports.
-prepare the table where you're gonna install the components.
-install the CPU and CPU cooler (motherboard outside the case). Insert single RAM module, connect the monitor to the motherboard (if onboard graphics available), power the board and start it. This way, you'd know that the board does work.
-prepare the case - insert the board I/O shield and standoffs in the correct locations (each standoff should match a board screw hole). Install the case extra fans (if you decide to add some).
-identify the case cables (read the manual of the case).
-install the power supply.
-install the motherboard. Connect the power supply to the motherboard (read about cable management).
-test again if board working (getting signal on the monitor).
-install all other components.
That's it.
